This gearin'g' ise nveiitionaland is fully illustrated on pageants- 45,-ine1usive, of the last-named catalog. The cone pulley 20 has integral therewith a shaft *2l Whirl-h ism'ou'rited in a bearing 22 in the seme Elena has'a beveled ear 23 en the end tn ot. cenepuuey 20 has a belt-25 thereon Whi V is-alshhlountedbn a dne'pulIey 26 which lly ha'sl aiiinioh on the left'fhand end thereof h mes L {with a pinion 21 on a shaft 28 Whicheiitnd into a gear box29 where shaft28 h fixed on hel'end thereof a beveled gear 30 which is atlapte d to mesh one at a time with beveled fgea'is 3'! 7 nd 32which are integral with each ether and-being secured on a sleeve 33 iiiid bhfafshafhfl extending from the box 29. The -sle'eve 'ili, is-l'zeyedior sliding movement on the shaft 34 and has a peripheral groove 36 therein adapted to be engaged by a pin 31 (Figure 4) on one end of a lever 38 pivoted as at 40. This lever 38 has an arcuate slot 4I therein for cooperation with the other parts of the machine not necessary to describe for an understanding of this invention.

The pivot pin 40 rises upwardly from a housing 42 and the housing 42 rotatably mounts the lower end of a shaft 43 on the lower end of which is mounted a disc 44 (Figure 6), and immediately thereabove is an eccentric cam 45, all of which is shown in plate F12-BD in said roving frame catalog of parts. The lever 38 is hooked at its end nearest the observer in Figure 4, forming a cavity 46, in which the eccentric cam 45 has movement. The disc 44 which is disposed immediately below the cam 45 and fixedly secured on shaft 45 (Figure 6) has two pins 41 and 48 extending downwardly therefrom which are engaged by a lever 50 pivoted as at I and pressed against one of the pins 41 or 48 at a time by means of a tension spring 52 anchored to a spring perch 53 anchored on the Samson I0.

The arrangement just described, comprising the lever 50 urged by Spring 52, tends to urge the shaft 43 to rotate in a clockwise manner looking down from the top of Figure 2 or looking down on Figure 6, the purpose of which will be later described. The shaft 43 has fixedly secured thereon a hub member 55 having arms 56 and 51 extending therefrom. The shaft is rotatably mounted in a L-shaped bracket 58 and immediately above the horizontal portion of the L-shaped bracket 58 there is fixed on shaft 43 a worm 60. The shaft 43 projects upwardly through a bearing BI and on its upper end has fixedly mounted thereon a beveled gear 62 which beveled gear is segmental in that it has disposed 180 degrees apart from each other blank spaces of about de rees each designated by reference character 63 (Figure 3). Thus it is seen that the spring 52 tends to urge the shaft 43 to rotation to cause one of the toothed portions of beveled gear 62 to engage the beveled gear 23 when permitted to do so by movement of one of the arms 56 and 51 past a vertical reciprocating mechanism, to be presently described.

The bracket 38 has disposed therein a stub shaft 65 on which is rotatably mounted a worm gear 65 having a hub portion to which the reference character is applied in Figure 3, which meshes with worm 00. There is also rotatably mounted on the stub shaft 65 a pinion 61 disposed in spaced relation to the worm gear 66 and between the worm gear 66 and pinion 61 is disposed a clutch mechanism 68 which at times is adapted to declutch the worm gear 66 from the pinion 61. This happens when the stop motion mechanism is operated as will be presently described. v

The pinion 61 meshes with a tension compound gear 18 rotatably mounted on a stud bolt 1| and also integrally driven, but separable from the pinion :"0, is a change gear pinion 12 which meshes with the lower toothed portion of the conventional rack 13 of the roving frame. The clutch 68 has extending therefrom an arm 14 which is slotted as at 15, in which slot there is disposed for movement 2. pin 15, fixed on the lower end of a stop motion lever 11 which is pivoted as at 18 on the bar :2 and projects upwardly and is secured as at 80 to a shipper shaft M which is connected to the conventional belt shifting or other stop motion mechanism of the roving frame.

Pivoted to the lever 11 as at 82 is one end of a lever 83 which is notched to provide a shoulder 84 and which lever 83 projects through a suitable opening 85 in the Samson I0 and the shoulder 84 is adapted to engage the left side of a plate 86 secured to the Samson I0 to prevent its normally moving to the right in Figure 2.

Thelever 11 is normally urged in a counter clockwise direction by means of a tension spring 81 secured at one end near the lower end of the lever i1 and at its other end to an adjustable spring perch 88 .secured to a bracket 89 mounted on Samson I I. When the lever 11 has been moved to the position shown in Figure 2 to stop the mar chine, this actuates the conventional clutch 68 and declutches the Worm gear from the pinion 61 and thus allows the rack 13 to be manually restored to starting position.

Secured on the Samson I0 is a bracket 90 in which is rotatably mounted a vertically disposed stub shaft 9| having a pinion 92 fixed thereon which meshes with the side teeth 93 in the rack bar 13. On the upper end of shaft 9| is fixed a pinion 94 which meshes with a pinion 95 forming a part of a tube gear which has integral therewith a tubular portion 96 which has on its upper end a pinion 91. The pinion 91 meshes with a pinion I00. The pinion I00 is mounted on the lower end of a shaft I0! which is rotatably mounted in a bearing I02 integral with a bracket I03 secured on one side of the Samson I 0. The shaft I 0| projects upwardly and has a hand wheel I04 fixed on itsupper end which can be turned for resetting the rack 13 and associated parts to initial position.

The pinion I00 meshes with the pinion 91, previously described, on the upper end of sleeve 96. The sleeve 90 as well as the pinions 95 and 91 have a squared hole passing longitudinally thereof in which is slidably mounted a squared shaft I05. One side of the Samson I0 has a vertically extending rib I06 on which is slidably mounted a vertically extending block I 01. This block I0! has extending forwardly therefrom an arm I08 which is secured by any suitable means, such as a screw I09, to the lower surface of the bolster rail I4 so that up and down movement of the bolster rail will likewise move the block I01 up and down.

The block I01 has a pair of stub shafts I I 0 and III projecting rearwardly therefrom, the other ends of which support a plate I I2. The plate I I2 has spaced bearings H3 and H4 in which the shaft I65 is rotatably mounted. The shaft I05 has two oppositely threaded portions H5 and I I6 thereon.

Threadably mounted on threaded portion II5 is a bracket II1 which has vertically disposed portions ,II8'and II9 integral therewith. The plate H2 has an outwardly projecting portion I20 which prevents rotation of member II1 as well as a member I2I threadably mounted on the lower threaded portion IIB of shaft I05.

The member I2I has integral therewith an upwardly projecting portion I22 which is likewise adapted to engage the portion I20 of plate II2 to prevent rotation of the member I2I, The member I2I has a vertically disposed and downwardly projecting portion I23.

The above described parts are conventional parts in a Saco-Loweli roving frame of several types such as the D type or the J-3 type andthe like. It is with this mechanism that this stopmotion mechanism is adapted to cooperate. p

Method of operation "The parts are shown in'Figure l in operative condition while the machine is properly running, and in Figure2, the parts :areshown in the positionhthey will occupy when the machine has been stopped due to the fact that the builder motion has moved upwardly too far. position of parts as appears in Figure 2 would also occur when the builder motion moves down too far to cause the lip I60 to engage the tongue I54, except that angle bar I40 would be swung in a counterclockwise direction.

During the normal operation of the machine, the up-and-down movement of the bolster rail will cause the block Ifl'I to move upwardly and downwardly, and the shafts H0 and III will cause the plate II2 likewise to move upwardly and downwardly during a building operation. This will cause the brackets Ill and I2I along with the shaft I05 to move upwardly and downwardly since the upper end of shaft I05 has sliding movement in the sleeve 96. This movement will cause the tongue IE! not to rise far enough to engage the arm I54 and likewise upon downward movement, the projection I68 will not engage arm I54 to move the quadrant I50.

As has before been described, the spring 52 is pushing against one of the pins 41 or 48 and is tending to rotate the beveled segmental gear 62 to where it will engage the constantly driven beveled gear 23. The brackets Ill and HI will move down just far enough to let arm 56 pass, and likewise will move just far enough upwardly to let arm 51 pass during the normal operation of the builder motion, for as the brackets I I1 and I2! move up and down, arms 56 and M will alternately be sliding along the ribs I22 and H8, respectively. As the builder motion reaches its lowermost position, the arm 51 will pass by the upper end of surface H8 and allow the spring 52 to urge the shaft far enough to where one of 4 'The same 0 foeiatetl parts so that the tension inth'e spring 52 Will ilht be '--S1ifiient to iilitiate rotatibn ill: t Shaft 43 to reverse the builder mechanism,
